“…The first impregnation, known as the wash coat, includes a suspension of aluminium oxide with a mixture of cerium oxides, lanthanum and neodymium ions in nitric or/and citric acid, used as a dispersant [1]. A second impregnation involves the platinum group metals (PGMs), typically as nitrate salts of Pt, Pd and Rh dissolved in nitric acid.…”

The reduction of palladium, rhodium and neodymium ions at concentrations of 0.94, 0.97 and 0.69 mol dm -3 , respectively was studied in 1 mol dm -3 HNO 3 or 1 mol dm -3 HCl, at a stainless steel and a vitreous carbon electrode, at 25°C. At a vitreous carbon electrode in a solution containing rhodium and palladium ions in 1 mol dm -3 HCl electrolyte, the reduction of metal ions occurred at a similar potential to the formation of hydrogen gas, which impeded the selective separation of the two metals. At a stainless steel cathode in 1 mol dm -3 HNO 3 , palladium deposition occurred at a potential &0.35 V less negative than that of rhodium allowing the selective recovery of palladium. Neodymium ions were not electroactive in acidic chloride or nitrate media at pH 0. Using a solution obtained from a catalytic converter manufacturer containing palladium, rhodium and neodymium ions in 1 mol dm -3 HNO 3 , palladium ions were preferentially removed at 0.15 V versus SHE at an average cumulative current efficiency of 57%.

“…The noble metals used in practice are Pt and Pd and usually supported on an oxide like ZrO 2 , Al 2 O 3 and SiO 2 or mixed metal oxides. 11,12 The objective of the present work was to investigate an efficient catalyst (Pt/ZrO 2 ) for the oxidation of toluene in aqueous solution at low temperature. There are, to the best of our knowledge, no reports concerning heterogeneous catalytic oxidation of toluene in aqueous solution.…”

The heterogeneous oxidation of toluene in aqueous medium has been investigated. Artificially contaminated water with aromatic compound (toluene) was exposed to a simple platinized zirconia (1% Pt/ZrO 2 ) catalyst in the presence of molecular oxygen. This selective oxidation of toluene to benzyl alcohol, benzaldehyde and benzoic acid provides a step for removing toluene from wastewater or converting it into less harmful substances. Different parameters, e.g. the reaction time, temperature, pressure, the amount of catalyst and agitation, etc influenced the toluene conversion and selectivity. Typical batch reactor kinetic data were obtained and fitted to the classical Langmuir-Hinshelwood model, Mars-van Krevelen model as well as to the Eley-Rideal model of heterogeneously catalyzed reactions. The Eley-Rideal model was found to give a better fit. 1% Pt/ZrO 2 was observed to be the most active for oxidation of toluene at 333 K in oxygenated atmosphere [p(O 2 ) ca. 101 kPa] with a nominal stirring speed ≥900 r/min. It was found that catalytic oxidation may be an effective method for the removal of volatile organic compounds from aqueous solutions and comparable to other advanced oxidation processes.
